Here is my onchange code that gets the error :

def onchange_asset_id(self,cr,uid,asset_id,qty,bal_units,context=None ):
    tot = 0
    rem = 0


    rental_id = None


    value = {'value':{'asset_id': ''}}
    with_asset = 0.0
    rental_obj = self.pool.get('fleet.rentals')            
    rental_id = context.get('rent_id')
    if rental_id:
        for rid in rental_obj.browse(cr,uid,[rental_id],context=None):

            sqlreq = "select sum(qty), asset_id " \
                     "from fleet_rentals fr ,fleet_rentals_line frl " \
                      "where fr.id = frl.rent_id and asset_id = " + str(asset_id) + " " \
                      "and frl.id != " +str(rental_id) + " " \
                      "group by  asset_id "


            cr.execute(sqlreq)

            resline =  cr.fetchall()

The error message is this :

 rental_id = context.get('rent_id')

The error is from this part of the code. .get function used on context is a dictionary function. But The type of context in the function here is Not a dictionary and thats why the error.

it would be better to use this code.. 

def onchange_asset_id(self,cr,uid,asset_id,qty,bal_units,context=None ):
    tot = 0
    rem = 0
    if context == None:
        context = {}

rental_id = None
value = {'value':{'asset_id': ''}}
with_asset = 0.0
rental_obj = self.pool.get('fleet.rentals')            

if  type(context) == dict and context.get('rent_id'):
    rental_id = context.get('rent_id')
    for rid in rental_obj.browse(cr,uid,[rental_id],context=None):

        sqlreq = "select sum(qty), asset_id " \
                 "from fleet_rentals fr ,fleet_rentals_line frl " \
                  "where fr.id = frl.rent_id and asset_id = " + str(asset_id) + " " \
                  "and frl.id != " +str(rental_id) + " " \
                  "group by  asset_id "


        cr.execute(sqlreq)

        resline =  cr.fetchall()

do it like this. you are getting None in context thats why you got this error.

 def onchange_asset_id(self,cr,uid,asset_id,qty,bal_units,context=None ):
     if context is None:
         context = {}

The line:

for rid in rental_obj.browse(cr,uid,[rent_id],context=None):

must be

for rid in rental_obj.browse(cr,uid,[rental_id],context=None):

Thanks for the answer.. But it seems that, that is not the reason why I got my error.. I updated my post and add the error message that appears..
